That flag works, but bleeds through fog and has some visible dithering / banding (probably not really noticeable in gameplay). It can be a bit too dark on grass as well. Main menu 1F Swamp 1F EDIT: for comparison: Swamp 2E | Swamp no AO It seems to flicker on/off in the same places (that I've tested) as the 2E and 32 flags. It does have greater draw distance (I think.. the other flags are very faint at range) and possibly better environmental coverage than 2E and 32 - if the fog bleeding and intensity (on grass/foliage) can be reduced by modifying the flag it might produce better results overall. ----- I'll try out the 0x000A0000 (Far Cry 2) flag in Fallout 4 later. For some reason I assumed only the 0x001xxxxx flags would work in DX11 games. EDIT: 0x000A0000 works, effect is fairly subtle with short draw distance. Seems to break in the same places as most of the other flags I've tested. Haven't noticed any fog bleeding. Water bleeding is present but relatively mild (and only appears at short range).
